During the transportation of oil, various oil‐spill incidents are reported. The utilization of oil sorbents for the treatment of oil spills is a promising approach among the all‐existing solutions. Nonbiodegradability and non‐renewability are the two major issues in the case of synthetic oil sorbents. In this review, the use of biodegradable polymers for oil‐spill cleanup is highlighted. In each section, the biodegradable materials and modifiers used, the method applied for a modification, the contact angle after modification, sorption capacities, and the reusability of developed biodegradable sorbents are extensively discussed. Mechanisms of biodegradation of biopolymers are also discussed. The manuscript also incorporates the recent developments in the fabrications of advanced sorbents with sustainable approaches along with challenges associated with current sorbents and future prospects.

“…10,11 Poly(vinyl alcohol) (PVOH) is a hydrophilic and watersoluble polymer which constitutes an ideal candidate for fabricating polymer aerogels because of its low toxicity, good chemical stability, and favorable mechanical properties. 12,13 Due to its properties, PVOH-based materials and aerogels have been efficiently used in many fields, such as acoustics, 14,15 reinforcers, 16 oil spillage applications, 17 antibacterial agents, 18 superabsorbents, 19 pressure-sensing applications, 20,21 among others. As such, there is an increasing interest in developing novel organic PVOH-based aerogels with superior properties.…”

Electric Conductivity Study of Porous Polyvinyl Alcohol/Graphene/Clay Aerogels: Effect of Compression

In this work, poly(vinyl alcohol) (PVOH)/graphene (GN) oxide/clay aerogels were prepared using montmorillonite (MMT) and kaolinite (KLT) as fillers. This work paves the way for the development of aerogels filled with MMT or KLT with high conductivity. The mechanical properties of the polymer/clay aerogels are enhanced by incorporating GN into these systems. These composite materials have an enhanced thermal stability, and the combination of PVOH and GN leads to interconnected channels which favored the conductivity when a clay (MMT or KLT) is added to the mixed PVOH/GN matrix. However, after compressing the samples, the conductivities drastically decreased. These results show that the design of solid MMT/GN and KLT/GN composites as aerogels allows maximizing the space utilization of the electrode volume to achieve unhindered ion transport, which seems contrary to the general design principle of electrode materials where a suitable porous structure is desired, such as in our uncompressed samples. These findings also demonstrate the potential of these materials in electrodes, sensors, batteries, pressure-sensing applications, and supercapacitors.

Rigid poly(vinyl chloride) (PVC) exhibits limitations in mechanical performance and thermal stability. The aim of this study is to develop composite and nanocomposite materials with enhanced properties using zinc oxide (ZnO) as a filler to address the limitations of rigid PVC. The objective is to produce a cost‐effective material with improved thermal stability and mechanical properties. To enhance dispersion and compatibility with PVC, the ZnO filler was surface‐treated with stearic acid through a mechanical treatment process. The PVC/ZnO composites were prepared via melt mixing using a Brabender plastograph. The Fourier transform infrared spectroscopy and x‐ray diffraction results indicate that the surface treatment significantly altered the ZnO microstructure, leading to improved ispersion within the PVC matrix. Consequently, this modification resulted in enhanced properties of the rigid PVC, with a notable improvement observed at a ZnO filler content of 2 wt%. The thermogravimetric results indicated that treated ZnO increased the thermal stability of PVC composites. The mechanical test (Tensile Testing) reveals that highest modulus of elasticity (2.8 GPa), tensile strength (41 MPa), and elongation at break (38%) was obtained with modified ZnO incorporation.Highlights Stearic acid improved ZnO filler dispersion and compatibility in rigid PVC. Treated PVC/ZnO composites showed better thermal stability and mechanical properties. FTIR, XRD, and TGA confirmed the surface treatment's impact on composites.
